Title: A process for separating non-lubricating hydrocarbon oils into their components
IPC: C10G21/04
Filed: 1934-07-12
Abstract: Mineral oils of viscosity lower than lubricating-oils, such as gaoline, kerosene, or gas oil are separated into their components by extraction with two solvents led in counter current in which one solvent consists of saturated preferably aliphatic hydrocarbons containing 3 or more carbon atoms, having a boiling range outside that of the oil being treated, and the other a solvent for non-paraffinic components.  Non-paraffinic solvents specified are liquid sulphur dioxide, furfurol, phenols, ketones, dichlordiethyl ether; aromatic or aliphatic nitriles or nitro-compounds such as nitrobenzene, nitromethane, nitronaphthalene, monochlor acetonitrile, naphthonitrile, benzonitrile; organic rhodanides, such as methyl rhodanide; amines such as aniline, naphthylamide; esters of mono- or polyvalent alcohols such as methyl or glycol formate; methyl or ethyl alcohol, aldehydes, such as thiophene aldehyde; nitroaniline or nitroanisole.  Diluents such as benzol, toluene, naphthalene and ether may be added.  Saturated hydrocarbon solvents specified are, propane, butane, pentane, hexane, nonane, hexadecane, gasoline, petroleum ether, paraffinum liquidum, refined spindle oil, paraffin wax, tetra- or decahydro naphthalene or naphthenes. The two solvents which are substantially immiscible may be introduced at opposite ends of an extraction column to which a temperature gradient is applied and the oil introduced at an intermediate point; or the oil may be mixed with one solvent and passed in counter flow with the second solvent; or the oil flowing in counter current with one solvent is treated over a part of the path with the second solvent, the resulting extract is drawn off freed from solvent and the residue re-introduced into the system. The extraction may also be effected in a series of mixers and settlers.  The two solvents used should have appreciably different molecular weights whereby the critical solution temperature is substantially higher than the extraction temperature; for example, the anti-knock properties of natural, cracked or synthetic gasoline containing aromatic, unsaturated and naphthenic hydrocarbons is improved by extracting with gas oil and nitro benzene or liquid sulphur dioxide; the cetene number of gas oil (Diesel fuel) is improved by extraction with light hydrocarbons or lubricating oil and furfurol or acetonitrile.  Kerosene for use as illuminating oil may also be treated.  The process may be effected under increased, ordinary or reduced pressure.  Distillates containing wax are preferably dewaxed before extraction.  The oils may be finally treated with sulphuric acid or a bleaching earth.

Title: Improvements in or relating to transistor circuits
IPC: H03K3/282
Filed: 1958-04-18
Abstract: 856,147. Transistor two-stable-state circuits. WESTERN ELECTRIC CO. Inc. April 18, 1958 [April 23, 1957], No. 12373/58. Class 40(6). A two-stable-state circuit comprises two junction transistors of opposite conductivity types with the base electrode of each directly connected to the collector electrode of the other and with the base and emitter electrodes of one transistor connected to a common output point through respective adjustable impedance arrangements. In the circuit illustrated positive pulses applied at terminal 30 trigger the circuit to a highconducting state while positive pulses applied at terminal 37 re-set the circuit to its low-conducting state. Resistors 20 and 27 are adjusted to achieve a comparatively low value for the current amplification factor of two transistors considered as an equivalent transistor having an emitter electrode 21, a base electrode 22 and a collector electrode 23, thus ensuring that re-set current required at terminal 37 need not be excessively large and that the leakage currents flowing are not so large as to maintain the circuit permanently in its highly-conducting condition. The inductor 26 results in the circuit having instantaneously a very large equivalent current-amplification factor when it is being triggered from its low-conducting to its highly-conducting condition thus assisting in the switchover which when the circuit is being re-set the current maintained flowing by the inductor 26 shunts the transistor 11 so resulting in a small equivalent current-amplification factor and assisting the re-setting action. Specification 753,014 is referred to.
